Automated regression testing using DBT and Sleuth

SUMMARY Regression testing is an important activity in software maintenance. Current regression testing strategies can be categorized into two groups: retest all and selective regression testing. Each of these two groups encompasses a variety of strategies. In industrial practice, regression testing procedures vary widely. Sometimes, several regression testing techniques are used in combination. Technique selection is also innuenced by the expected quality of the system to be tested. Such variations in regression testing strategies and techniques mandate exibility for a regression testing tool. This paper presents regression testing support for Sleuth, a test generation tool based on Domain-Based Testing. We explain the rules for building regression tests for a variety of possible regression testing strategies from retest all strategies to selective regression testing strategies.
